问题
I have an ASP classic application that I'm migrating from a Windows 2000 to Windows 2012 Server.
It uses the following code to import xls files
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open "DRIVER={Microsoft Excel Driver (*.xls)}; IMEX=1; HDR=NO; Excel 8.0; DBQ=" & Server.MapPath("\Imports\") &"\"&fn& "; "
and the following for csv files
Set objConn = CreateObject("ADODB.Connection")
Set objRS = CreateObject("ADODB.Recordset")
objConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strPathtoCSVFile & ";Extended Properties=""text;HDR=YES;FMT=Delimited"""
As per the answer on this question Excel ODBC and 64 bit server I downloaded and installed the Microsoft Access Database Engine 2010 Redistributable.
I've tried both the 32bit and the 64bit version of the above but neither of them work unless I change the application pool setting Enable 32-bit applications to True. If it is set to False I get the below error.
Microsoft OLE DB Provider for ODBC Drivers error '80004005'
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
Unfortunately setting it the True breaks PDF rendering in another part of that website.
The only viable option I have come up with so far is to set this part up under it's own application pool that is 32-bit.
How can I run this in 64-bit Application Pool?
EDIT: And before someone comes along with a dupe hammer, a related question that does not resolve the issue is ASP running in 64 bits environment with Access database
回答1:
First, make sure you install the 64-bit package AccessDatabaseEngine_x64.exe successfully.
After that, use the following connection strings.
You should no longer have problems working with your 64-bit application pool.
'Excel 97-2003
Set Connection = Server.CreateObject("ADODB.Connection")
Connection.Open _
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\my\path\to\tables.xls;Extended Properties=""Excel 8.0;HDR=NO;IMEX=1"";"
Set Recordset = Connection.Execute("Select * From [Sheet1$]")
'CSV / TXT
Connection.Open _
"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\my\path\to\csv_dir\;Extended Properties=""text;HDR=YES;FMT=Delimited"";"
Set Recordset = Connection.Execute("Select * From table.csv")
connectionstrings.com has always been a good reference for connection strings.
